The halogenoalkane is heated under reflux with a solution of sodium or potassium hydroxide.
Heating under reflux. It is used in industrial and laboratory distillations. Oct 8, 2022 · The term ‘reflux’ describes an arrangement in which a reaction is carried out in a boiling solvent with the vapour being condensed and returned to the reaction vessel.
Why do you need.
. understand. How does reflux work in organic chemistry? Reflux involves heating the chemical reaction for a specific amount of time, while continually cooling the vapour produced back into liquid form, using a condenser.
In chemistry, azeotropic distillation is any of a range of techniques used to break an azeotrope in distillation. Reflux is a chemistry lab technique that heats a solution, produces vapor, and then condenses and returns the outgoing vapor into its original mixtures.
